- To all "whom it may concern:

Be it known that I, GEORGE ONEILL, of 280 High street, in the city of Moncton, in the Province of New Brunswick, Dominion of Canada, have invented certain new and uesful Improvements in Smoke-Consumers,-

grate, all as hereinafter more fully set forth and described in the accompanying specification and drawings.

In the drawings, Figure 1 is a transverse sectional view through a steamboiler furnace embodying the present'invention. Fig. 2 is a sectional elevation taken at right angles to Fig, 1.

Like characters of reference refer to like. 1

parts in the several figures.

Referring to the drawing, A represents a boiler of any suitable type arranged sin ly or in batteries having suitable fire tu es therein andsupported in a suitable masonry" structure B.

C represents the fire grate and D the smoke box, both of 'usual construction.

f centage of the smoke may tend completely The smoke consuming device forming the present invention comprises a pair of U- shaped pipes F having horizontal parallel arms 12 and 13, the upper horizontal arms projecting through the masonry structure into the smoke box and being formed with ownwardly opening flaring ends 14, the flaring mouths meeting at the center to form a V-shaped deflecting shield 15 which divides the products of combustion between the two mouths. These mouths are located ust above the opening of the tubes and exk b 11 1 across the front o t? f" smo e ox w 1 e occu onl art-o1 width of the same s o iliit a be rtain perpass directly to the stack G. The lower parallel arms of the U-shaped pipes F project through ti-i: inasonry structure to beneath'the grate and are formed on the outer end with branch connections 17, which branch connections discharge across the vertical portions 18 of the pipes F the said branch connections having air valves 19 in their outer ends of any suitable type and steam jets 20 extending through the center of the air valve, the said steam jets having suitable controlling valves 21. In the smoke box above the V- shaped shield 15 and protected by the shield from the products of combustion a T-piece 22 is provided, connected to steam jets 23 and 24; which project into the arms 12 and to a supply pipe 25 for live steam.

In, operation the steam jets 23 and 24 will entrain a portion of the products of combustion and smoke from the smoke box and cause them to pass through the pipes F and discharge through the parallel arms 13, at

the same time the jets 2O discharging across the vertical portions 18 will assist in the circulation and will also entrain regulated quantities. of air through the valves 19.

As many changescould be made in the above construction and many apparently Widely different embodiments of my invention, Within the scope of the claim, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanyingspecification and drawings shall be interpreted as illustrative and not in a limiting sense. 7

What I claim as my invention is:

smoke consumer comprising in combi nation, a boiler having a fire grate, a smoke box, a supporting masonry structure, U- shaped pipes, the parallel arms of which are horizontally disposed, the upper parallel arms being designed to projectv through the masonry structure surroundingthe a boiler and into the upper part of the smoke box, the lower parallel arms of the pipes being designed to project-through the masonry structureand beneath the .fire grate, branch connections for the lower arms open at the ends, air valves in the outer ends of the branch'connections, steam jets extending in the branch connections and discharging across the vertical portion of the U- shaped pipes, flaring mouths formed on the inner ends of the upper parallel arms, said 5 steam, and steam jets leadingfrom the T- Witnesses:
